16 Of The Most Disturbing Facts You’ll Ever Read That’ll Leave You Thinking, “Alright, That’s Enough Internet For Today”

Note to self: Ask for no ice the next time you go out to eat.

Recently, Reddit user u/Bancoarotelle asked, "What is the most disturbing thing to know?" and boy am I disturbed.

1. "During World War 2, Japan bombed China with fleas infected with the bubonic plague."

This attack was known as the Kaimingjie germ weapon attack, where Japanese troops, including ones from Unit 731, dropped corn, wheat, and cotton infested with fleas carrying the bubonic plague, cholera, typhoid, and other diseases in Chinese cities to start an outbreak. The infested areas were burned down, but it's estimated that this attack, among others, resulted in about 300,000 deaths.

2. "There are about six US nuclear weapons that are currently unaccounted for."

They call this "empty quiver," when US nuclear weapons are stolen, lost, or taken. It's also considered the worst-case scenario, so I'm just going to start setting up my bunker now.

3. "That there are anywhere between 25–50 active serial killers in the United States, according to the FBI."

4. "Polar bears are the only bear species that actively hunt and kill humans for food. There’s a rhyme that everyone living where bears live needs to know, and why the rhyme is so important: If it’s brown, lie down. If it’s black, fight back. If it’s white, say goodnight."

"Brown or grizzly bears will leave you alone if you play dead. Climbing up a tall tree works with adult brown bears since they can’t climb trees. Black bears will back off when they realize you’re more of a threat than they realize, but DO NOT climb a tree to escape. Both cubs and adult black bears can climb trees. Polar bears are not only the largest bears, but they are ambush predators. If one manages to sneak up on you, you’re as good as dead."


5. "By the time you show the symptoms of rabies, it's already too late. It can also be dormant for a year before you show those symptoms."

It's extremely rare to recover from rabies if you don't get treated right away. Even if you don't feel or notice a bite or scratch, it's better to be safe than sorry!

6. "If an elephant's mate dies, then they can die from broken heart syndrome."

Also known as takotsubo cardiomyopathy, "broken heart syndrome" is basically a stress-induced heart attack and can affect both humans and animals. So yes, dying of a broken heart is very real.  

7. "Cruise liners all have a morgue for all the passengers that inevitably die each trip."

For lines that carry older customers, it's estimated that the cruises have three deaths per week.

8. "HVAC technician here. NEVER TRUST RESTAURANT ICE. Ice machines need to be fully dismantled for cleaning every couple of months or so in order to remain sanitary."

"And [the] whole procedure takes time and destroys the restaurant's entire ice supply if we're servicing their only machine, and restaurants don't want it done because their profit margins are so thin as it is. If the machines aren't cleaned, they slowly fill up with mold, and what we fondly call 'Pink Slime,' which is a colony of solid bacteria that has grown so large that you can literally pick it up out of the machine's water tank."


9. "The CPR dummy face template is based on a dead 16-year-old girl’s face. Her body was pulled from the River Seine in the 1880s, and her cause of death and identity were never discovered. A mortician was so ‘entranced’ by her peaceful expression that he made a plaster mask of her, which became the face of CPR dummies and health training equipment."

10. "That slavery is still one of the biggest profiting trades in the world."

According to the UN, there are 40.3 million slaves worldwide. You can even find out how many slaves are contributing to your lifestyle, including the clothes you wear, the electronics you use, and the food you eat based on research conducted by Slavery Footprint.

11. "If you try to grab the brain in its natural state, it will fall apart. When you see scientists pick up the brain, they have used chemicals to harden it."

Brains are very soft and VERY easy to deform, hence why they float around in cerebral spinal fluid to keep them from hitting our skulls. Just another reason why wearing a helmet is probably the most important thing you can do. 

12. "There is value to the human body as a commodity. And different parts of our body are worth different amounts — while corneas are small, they fetch a large price (£15,000, or about $22,450), whereas our skeleton garners significantly less (£5,000, about $7,483)."

"The price also depends on whether the body part is sold for specimen use, transplants, or on the black market."


13. "Early childhood malnutrition (between ages 0–5) causes irreversible loss of IQ (11–20 points) and predisposes people to higher levels of violence. The prefrontal cortex doesn't develop the same. And if you miss that window, there's no intervention that can recover the gap."

An example of this is Genie, who was abused so badly by her father in the 1960s between the ages of 1 and 13 that she never learned to fully communicate and has been ward of the state of California ever since. 

14. "One-third of all people who break their hip die within the year... So please tape pillows to your elderly relatives."

Older adults are five to eight times more likely to die as a result of a hip fracture than those without, and the rate increases by 4% every year. 

15. "The liver can be ruptured in one punch. The liver is the second most fragile organ in the human body."

The most fragile organ in the human body is, you guessed it, the brain.

16. And finally, "A tumor can have teeth and eyes."


They're called teratomas, and they occur most often in ovaries and testicles. They're VERY rare, though, and they can be benign, so no need to worry too much about it. But it's quite gnarly to look at, so just spare your eyes and use your imagination.
